| weather | the condition of an area over a short period of time |
| greenhouse effect | when the atmosphere of the earth reflects some radiation, and the radiation it does keep in is kept longer by the portective layer. |
| revolution | one complete orbit of the earth around the sun |
| tropic of cancer | where the suns rays hit the most directly |
| spring/fall equinoxes | mark of season change march 21 and sep 23. around these days the night and day are equal everywhere |
| precipitation | all the forms of water that fall to earth from the atmosphere, including rain and snow |
| orographical precipitation | when warm, moist air is forced upward over high landforms. this type occurs most frequently on seacoasts when ocean winds blow towards the inland mountains and it cools |
| evaporation | first stpe in water cycle when water from earths surface turns into condensation in clouds |
| atmosphere | a multilayered band of gases, water vapor, and dust above the earth |
| rotation | the spinning motion of the earth, like a top on its axis, as it travels through space |
| length of a year | 365 days |
| tropic of Capricorn | where the suns rays hit most directly in the winter solstice |
| climate zones; tropical, temperate and polar (latitudes) | tropical-low-latitudes/ hot all year...middle latitudes-cooler then torpical...polar-high latitudes are bitterly cold |
| water cycle | the process how water evaporates, turns into condensation, and returns back to earths surface by precipitation |
| frontal precipitation | when different temps meet. warm air is pushed up by cold air and cools |
| 3 influences of climate | bodies of water, landforms and elevation |
| climate | the term used for the weather patterns that an area or region typically experiences over a long period of time |
| axis | the invisable line that runs through the center of the earth from pole to pole. The earths axis is at 23.5 degrees tilt |
| leap-year- date | feburary 29 |
| summer/ winter solstice | changes in season when the sun rays are most direct at the tropic of cancer and capricorn.june 21 and dec 21 |
| convectional precipitation | occurswhen hot humid air rises and cools, losing its ability to hold in water. occurs near equator |
| fronts | boundaries between two masses of air that differ in density or temperature |
